Amorphous graphite is a naturally occurring seam mineral that forms from the geologic metamorphism of anthracite coal. Contrary to the name, �amorphous� graphite is not truly amorphous, but is a microcrystalline form of natural graphite. The morphology of amorphous graphite is typically granular...

Flake graphite is a naturally occurring form of graphite that is typically found as discrete flakes ranging in size from 50-800 micrometers in diameter and 1-150 micrometers thick. This form of graphite has a high degree of crystallinity, which equates to near theoretical true density, high thermal...

Calcined needle coke is a variety of petroleum coke (see section on petroleum coke for a basic introduction to PC manufacturing). The term �needle� is used to describe the acicular morphology of the coke since it tends to form oriented needle-like structures that are clearly visible to the naked...

Pitch coke is a high purity carbon residue manufactured by the destructive distillation (coking) of coal tar pitch. Coal tar pitch is a by-product resulting from the thermal distillation of bituminous coal. Because it is condensed from the gas phase, coal tar pitch is inherently low in ash and...

Synthetic graphite is a manufactured product made by high-temperature treatment of amorphous carbon materials. In the United States, the primary feedstock used for making synthetic graphite is calcined petroleum coke and coal tar pitch, both of which are composed of highly graphitizable forms of...

Activated carbons are a group of carbon materials that have surface �functionality.� This functionality results in materials that are effective at adsorption of certain chemical species. Active carbons are typically manufactured from �organic� precursors such as cellulostic materials (coconut...

Asbury offers a comprehensive line of water- and solvent-based graphite coatings, formulated for high-performance dry lubrication, release, electrical conductivity or thermal resistance, depending on the demands of your application. We also offer a complete line of specialty greases, as well as...

Carbon fibers are the state of the art when it comes to high strength, high modulus fibers. Carbon fibers are manufactured by spinning a suitable polymer precursor and thermally treating the resultant fiber to optimize its mechanical and chemical properties. Precursors are chosen to be materials...

Carbon black is a unique amorphous carbon solid that is manufactured by the deposition of solid carbon particulates formed in the gas phase. In general, it is manufactured by combustion or thermal cracking of a hydrocarbon fuel under reducing conditions. Carbon black has the finest primary...

Petroleum coke is a manufactured carbon product produced at a limited number of oil refineries. Petroleum coke results from the thermal processing of residual oil, which has been cracked or otherwise processed to remove low boiling fractions. Coke is made by heat-treating the residual oil (more...
